CCA Maryland is a proud partner of Calvert County Public Schools to support reef ball building with each 5th grade class in the county through their CHESPAX program.  

Volunteers are welcome at each reef ball build, but must complete the volunteer link below before supporting the event.

Additional volunteers are requested to support the towing of trailers to and from schools.  Interested parties should have a 1/2 ton or greater vehicle and will be offered reimbursement for the mileage driven in support of the program.  Transportation volunteers may sign up via email or call/text to David Sikorski for more details.  davidsikorski@ccamd.org or (443)621-9186

Calvert County Volunteer Policy.

In order to volunteer with students enrolled in Calvert County Public Schools, you must first register with the school system as a volunteer. Once approved, visit the elementary school where you plan to volunteer to have your ID scanned. **If you have been through this process already during the 2021-2022 school year, you do not need to register again until the 2022-2023 school year begins.

  1. Go to this link to register to volunteer with Calvert County Public Schools:

Become a Volunteer – Calvert County Public School District (calvertnet.k12.md.us)

Follow the Online Volunteer Application Process.  **Be sure to choose ‘CHESPAX’ as well as the school(s) where you will be going to volunteer, especially if you plan to go to more than one school.

You will receive an email notification when you are approved. This could take up to 2-3 days.

  1. Once you receive the email notification that you have been approved, you are good to go to the school on the date you have signed up to volunteer. Be sure to bring your driver’s license or state issued photo ID!
  2. When you arrive at the school, you must go to the main office to sign in as a volunteer and have your ID scanned. The secretaries there can assist with this step. You will then obtain a name badge which must be worn and visible at all times.
  3. At the end of you volunteer shift, you must return to the main office to sign out.
  4. On the return day, you must sign in as a volunteer, but you will not need to scan your ID again.

**Masking is now optional while on CCPS property and inside all CCPS buildings.

Reef Ball Build FAQs

What is a Reef Ball?

Reef balls are a specially designed artificial reef unit that are used worldwide to build and restore reef habitat. Here in the Chesapeake, reef balls provide important three-dimensional habitat for oysters and many other filtering organisms to attach to. They also provide hollow structure for juvenile fish and crabs to hide from predators. Yes, it’s those predators we pursue as anglers, so reef balls also make some great fishing spots too.

What am I volunteering to do?

Volunteers will be working on behalf of CCA Maryland. You will be outside in teams (or individually) to assemble reef ball molds and then help fill the reef balls with concrete delivered from a truck.

Bathrooms are available, as well as a place to sit in the shade and enjoy your lunch or take a break.

This is a simplified version of what we do for the Living Reef Action Campaign when working with students or other partners.  For most reef ball builds, we hand mix concrete or use small electric mixers.  For others, a concrete truck will arrive and you will help fill the molds you’ve assembled using gravity as your friend.

Depending which day you attend, you may remove the molds from previously built reef balls first and set molds up for another pour later that day.

Can I bring a group of friends or colleagues?

Yes!  There is no maximum sized group to participate.  We will aim to build around 25 reef balls per day, and can likely add to that number with additional molds for the right group.

To discuss organizing a reef ball building activity for your group or company, please contact David Sikorski at (443)621-9186 or via email to david@ccamd.org.

What should I wear?

We’d recommend long pants and multiple layers in light colors. For one, lighter colors are cooler in the sun. What’s the second reason? Some say that biting flies seem to be more attracted to darker fabrics.

Bring layers and changes of clothes based on your own assessment of the weather. We have gloves you can borrow. Closed toed shoes are best, especially ones that you can get dirty.

I'm ready to RSVP, what's next?

When filling out the form, first select “Reef Ball Build” as your area of interest.

Next, click the Select and Event button and select this date.  You may submit multiple applications for volunteering.

The RSVP is largely used so we can communicate with you leading up to the event and let you know if there are any changes due to weather, or other common logistical headaches.

When you volunteer, your name is added to a list for each day, and whoever is in charge of that days work will communicate with you.

If you have trouble getting in touch with someone or with our system.  Please contact David Sikorski @ 443-621-9186.  A text message may be the quickest way to connect with him and schedule a time to talk.
